A spherical container has a radius of 1 yard. It is filled with a liquid fuel that costs $10 per cubic yard.

joja [24]

Answer:

$41.86

Step-by-step explanation:

Radius of container = 1 yard

Volume of sphere = $\frac{4}{3} \pi r^3$

= $\frac{4}{3} \times 3.14 \times 1^3$

= $4.186 yard^3$

Cost of 1 cubic yard = $10

Cost of 4.186 cubic yard = $10 \times 4.186 =41.86$

Hence the total value of the fuel in the container is $41.86
